After that, the article covers the seven best options for translation software out there with recommendations for what to use for different purposes. Finally, we’ll show you how to use machine translation for translating your website.

What Is Machine Translation and How Does It Work?

Machine translation refers to the automated process of translating text or speech from one language to another using computers. Instead of human translators, it’s algorithms and — more recently — artificial intelligence that do all the heavy lifting.

As you will see below, there are many software solutions for machine translation out there. However, before considering using one, it’s critical that you understand the implications of doing so.

What You Need to Consider When Using Machine Translation

Not all machine translation providers are created equal. When choosing one, it’s important to use a reliable service in order to ensure:

  1. Translation quality — Accuracy and quality are paramount when it comes to translation. Reliable machine translation software has been trained on vast amounts of multilingual data. This ensures that what it produces is accurate and linguistically sound and that it conveys the intended message in the target language.

  1. Consistency — Consistency is vital, especially for businesses and organizations that use specialized terminology across various translated documents or platforms. A good machine translation solution adheres to predefined glossaries, style guides, and includes translation memory. That way, it makes sure that the same terms and phrases are translated consistently throughout for coherent output.
  2. Confidentiality and security — Language translation often involves sensitive information. This is especially true for legal documents, medical records, or business contracts. For that reason, it’s paramount that you choose a solution that prioritizes data privacy and security. Look for software providers that offer secure data transmission, encryption, and strict privacy policies to safeguard confidential information.
  3. Customization and adaptability — Different industries and domains have specific language requirements and terminology. Your software solutions of choice ideally allows for customization and adaptation to specific domains, providing industry-specific translations that align with the vocabulary and language conventions of your field. This enhances the accuracy and relevance of the translations.
  4. Ongoing support and improvement — Language is constantly evolving, and new phrases, idioms, and expressions emerge all the time. Reliable machine translation software providers offer regular updates and improvements to their systems, That way, they can ensure the translations remain up-to-date and reflect the evolving language trends. Additionally, they provide ongoing technical support to address any issues or concerns that users may encounter.

Benefits and Limitations Compared to Human Translation

weighing pros and cons of machine vs human translation

Compared to translation done by an actual person, machine translation offers several benefits but also shortcomings. Let’s go over those now.

Advantages of Machine Translation

First, the benefits:

  • Easy to use — You don’t need a lot of technical skill to make use of machine translation software. In most cases you simply pick your source and target languages, input the content, and you are good to go. Automatic translation is also easier to scale than hiring more human translators.
  • Fast — Just like mathematics or other complex mental tasks, machines tend to be faster at them than human beings, especially when you deal with a lot of content. Machine translation software can process thousands of words almost instantly, humans usually take a little longer than that.
  • Cheap — Another consideration is cost. Machines can do translations at a fraction of the cost of human translators. The latter starts at around $0.10/word at the low end, on the other hand, you can get 100,000 words translated by a machine for just $20. This makes it cost effective especially for high volume translations.
  • Integrate with other platforms — Most of the available machine translation software offer APIs to connect to other platforms and make their services available within different translation workflows. We’ll talk about an example for website translation further below.

Drawbacks of Using Machine Translation

Of course, machine translation also has areas where it’s not as good as human translations and that is:

  • Accuracy — While machine translation has gotten a lot better over the years, the highest accuracy it usually achieves is only about 90-95%, less if you have difficult language pairs. While that’s enough for some cases, for things like contracts, marketing material, or other content where language accuracy is absolutely crucial, it’s simply not enough. Human translators are also better at capturing original intent, not just converting words (see the difference between translation, transcreation, and localization).
  • Nuance — Machines don’t understand context and may struggle with accurately capturing the subtleties, nuances, and ambiguities of languages. Human translators, with their contextual and cultural knowledge, can provide more accurate and succinct translations.
  • Specialized knowledge — Finally, machine translation software often lack domain-specific knowledge and vocabulary. Translating specialized texts, such as medical or legal documents, requires a deep understanding of the subject matter, which machines may not have. Human translators with expertise in specific domains can do a better job here.

As is probably obvious from the above, for the best results, it makes sense to use both of these techniques together. That’s why these days machine translation is usually integrated into the tools that human translators use for their work.

7 Best Machine Translation Software Options

Alright, now that we have settled on what machine translation software is and what it can do, let’s talk about which options there are.

Using Machine Translation With TranslatePress for Automatic Website Translation

Now that you know your options for machine translation software, the question remains how to best use them to translate your WordPress website? It’s not always the easiest, especially if you are not a developer who knows how to work with APIs.

You can, of course, manually copy your content into the tools, translate it, copy it back, then reformat and publish it. However, as you can probably imagine, that’s not the most efficient way of doing things.

Another option is to use a WordPress plugin that integrates with machine translation software to automate much of the process. Luckily, that’s exactly what TranslatePress does. Here’s how our plugin can help you make automatically translating your website much easier.

Configure Machine Translation Settings

The first thing you need to do to use machine translation for your WordPress website is to activate it. For that, after installing and activating TranslatePress, go to Settings TranslatePress Automatic Translations. Here, the first step is to use the drop-down menu to set Enable Automatic Translation to Yes. Once that is done, you get access to the rest of the options.

You want to start by choosing your translation engine. In the free version of TranslatePress you only have access to Google Translate. Owners of a Business or Developer license can also opt for DeepL.

Whichever you pick, the next step is to input the API key for your machine translation software of choice. Check the instructions for Google Translate and for DeepL on how to obtain one. You can also use the link underneath the input field to find these.

When you have done that and saved, you are pretty much good to go. However, you might also want to look at the settings further below, where you can limit the characters to translate automatically per day.

This can be important to limit any costs you incur from these translation services as this is not something that runs through TranslatePress but something you arrange with the providers directly. The menu also shows the number of already machine translated characters per day.

Use Automatic Machine Translation

Once done with the configuration, using the machine translation is very easy. Simply click on Translate Site in the WordPress admin bar or TranslatePress settings.

Final Thoughts: Machine Translation Software

Machine translation can greatly accelerate the time it takes to convert your content or website into another language. By now, models have become so sophisticated that they are able to do the bulk of it for you quickly and easily.

Above, we have gone over a few of the best machine translation software providers out there. They are suitable for different use cases including website translation. However, to use them for this purpose, you either need to do a lot of manual work or possess enough technical knowledge to use the APIs they offer.
